Xapian devel - Sep 2012 - java-swig TermIterator

Hello,

Been using Xapian and the Java bindings for years, all was working
great, and I all of a sudden decided to upgrade to the latest 1.2.12 and
use the new java-swig bindings instead of the old hand-crafted JNI which
I think have been deprecated now.

I'm struggling with the new design of the TermIterator. More
specifically, I can't tell when I've reached the end of the list of
terms for my document.

If I keep calling next(), it will eventually crash in the C++ code and
cause the JVM to crash as well, fair enough.

If I call hasNext(), it always returns false, even though there are more
terms that I can actually retrieve by calling next().

If I try to compare my iterator to the termListEnd() of my document, it
always returns false as well. I've tried comparison with both == and
equals() just to be sure.

There must be something very simple I'm missing somewhere. Can somebody
give me some sample code to iterate through a TermIterator returned by
Document.termListBegin()?

Many thanks,
Eric.

Hey Eric,

That's correct. We'd like users to start moving to the swig bindings,
but honestly its not really ready.

There are a number of bugs in the current release of these
bindings. This is just one of them. I have been working on a lot of
fixes which I will hopefully be able to land soon. In addition, I am
working on properly implementing the Iterator interface for this
iterator and the others.

Unfortunately, this will not work properly now. I'm curious, have you
noticed other issues with swig bindings? Bug reports will be greatly
appreciated!
